Having issues moduling zootopia style fur
I am kind of where you are right now. I can give you some input maybe.


There might be a better way but a workaround at least is to duplicate the parts of the mesh and then separate them into a new object. That way you won't get hair in areas you don't want it. You can hide the emitter, so you only see the hair.
It will probably look better if you use more parents and less children.
Might be okay if you do it like answer 1.
You can set the thickness of the hair at the root and the tip. Yours is probably still set to 1 at the root. Try lowering it to 0.25
I am not sure, maybe related to question 2.
